Title: Method of Making a Non-Woven Fabric
IPC: D04H1/42
Filed: 1966-10-14
Abstract: 1,161,320. Laminated fabrics. JOHNSON & JOHNSON. 14 Oct., 1966 [18 Oct., 1965], No. 46009/66. Heading B5N. A method of making non-woven fabrics comprises forming a composite web of fibres, said web having at least three layers, two of said layers having between them an interlay 4 of fibres, constituting a third layer, having a denier at least twice that of the fibres in the layers on each side of the interlay, bonding the larger denier fibres and the smaller denier fibres with a bonding agent, and then splitting the web along the interlay. The fibres may be carded or randomly disposed and are laid down in a series of superposed layers. In one method layers 2, 3 and 4 all consisting of rayon fibres are superposed, impregnated with binder, e.g. a solution of an acrylic resin binder, such as Hycar (R.T.M.) by passing between wetted rolls, dried, heated to cure the binder, and split along the layer 4 by passing the composite web between a pair of rollers to form two non-woven fabrics each having one surface of larger denier fibres and the other of smaller denier fibres. In other examples given the outer layers are of rayon and the inner layer is of Dynel (R.T.M.) or a 50/50 blend of rayon and cotton, or the outer layers are a 50/50 blend of rayon and cotton and the inner layer is of rayon, or the outer layers are of cotton and the inner layers are of rayon, in which latter case a corn starch solution is used as the binder. Other fibres which may be used are linen, hemp, silk, wool, wood pulp, acetate, polyester, acrylic or neodacrylic fibres. In a further method the web comprises several interlays of larger denier fibres arranged alternately with layers of smaller denier fibres. Splitting is effected along each of the interlays to produce fabrics having the larger denier fibres on one or both surfaces.

Title: Generators of rate signals of digital type
IPC: H03M1/60
Filed: 1970-09-29
Abstract: 1306869 Analogue to digital converters BENDIX CORP 29 Sept 1970 [3 Oct 1969] 46157/70 Heading G4H [Also in Divisions H3 and H4]  A system for providing a digital signal corresponding to the rate of change of a measured variable such as pressure P for determining the rate of change of aircraft altitude, comprises a transducer 3 for providing an analogue error signal corresponding to the difference between the sensed value of the variable and an analogue signal derived from counter 8 by converting feedback circuit 5, an oscillator 12 which provides a pulse output at a frequency dependent on the error signal, a divider 60 for lowering the pulse frequency, a feedback loop for applying the lower frequency pulses to the counter 8 to reduce the error signal at a faster rate as the error signal increases, the frequency of the oscillator output corresponding to the rate of change of the variable and a circuit for converting the pulse output from the oscillator to the digital signal. The analogue error signal is fed to a voltage processor 10 which alters the limits of the swing of the signal to values suitable for the oscillator 12. The error signal becomes zero when the output from the counter 8 corresponds to the sensed rate of change of pressure, the zero value being defined by a pair of reference voltages. A sensor 6 stops the count when the error signal lies between the reference voltages. The output of the oscillator is a pulse train having a frequency proportional to the rate of change of pressure, the pulses being fed via a gate 62 and a counter 76 to a register 74 which provides the digital signal along with its sign supplied by a polarity sensor 7.

Abstract: 1,256,078. Transformers. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 27 Nov., 1968 [27 Dec., 1967], No. 46599/70. Divided out of 1,256,076. Heading H1T. An electromagnetic transformer coil for use in high temperature conditions has a resin encapsulated winding, its ends connected to insulated coated lead wires (polyimide-coated). The lead wires of the transformer coil are enclosed in a better insulation material than the wires of the coil which are impregnated with epoxy or similar resin. Since airtight encapsulation by epoxy resin composition prevents oxidation the coil will operate in a temperature range corresponding to lead wire insulation.

Abstract: 1305656 Toothed gearing OMP OFFICINE MECCANOPLASTICHE DI PRECISIONE SRL 1 Oct 1970 [4 Oct 1969] 46774/70 Heading F2Q [Also in Division H1] A stepping device, suitable for a washing machine programmer, provides intervals of different durations in any preset sequence and also provides for stopping the stepping for a prolonged period with automatic resumption thereafter. A motor 11 drives a gear 15 via reduction gearing (12, 13, 14, Fig. 2, not shown) and hence a gear 16 secured to gear 15. Gear 16 engages a further gear 17 but is only toothed over part of its periphery such that after a rotation of gear 17 through somewhat more than 90 degrees a spring 19 pressing on a doublenosed cam 18 can snap the gear 17 the remainder of 180 degrees rotation. An axial extension 22 of gear 17 carries two diametrically opposed ribs 23, 24 for co-operation with respective rings of teeth on a gear 10 which is coupled to a main programming cam block (not shown). The ribs 23, 24 are arranged to move in the path of the periphery of gear 10 during the rapid portion of the rotation of gear 17 which thus effectively moves in 180 degree jumps. Where teeth are omitted from the lower ring of teeth on gear 10 the rib 23 is ineffective and the interval between steps of gear 10 is doubled. Any desired sequence of single and double intervals may be preset by the pattern of omission of teeth on gear 10. If a tooth is omitted from both upper and lower rings on gear 10 the latter ceases to be driven and in order to provide automatic resumption of stepping a further partially toothed gear 26 is loosely mounted on shaft A and is normally driven by a pin 25 on gear 10 engaging the end of an arcuate slot (Fig. 4, not shown) in gear 26. Pin 25 is positioned with respect to the double missing teeth on gear 10 such that when the gear 10 ceases to be driven the rib 24 comes into engagement with the toothed portion of the periphery of gear 26 which is thereby stepped until the end of the slot therein entrains the pin 25 and moves the gear 10 one step forward whereby normal stepping is resumed and the toothless portion of gear 26 becomes adjacent to rib 24. A ratchet pawl (27, Fig. 4, not shown) holds gear 26 stationary until gear 10 has moved pin 25 on to the first end of the arcuate slot to step gear 26 until another prolonged interval occurs. The main cam block driven by gear 10 may be set manually, the rib 23 or 24 acting like a pawl on gear 10 under action of the spring 19 on cam 18. Cams R, connected to gears 15, 16, for continuous rotation, may be provided.

Apparatus for straightening motor vehicles comprises a horizontal beam 1 mounted on lateral support rollers 3, 5, means 8, 9 for fixing the work, an arm 13 pivoted on a horizontal axis 11 and having means 16 to connect it to the part of the work to be straightened, a second arm 12, means 18, 26 for respectively moving the arm 13 in a direction to exert a pull on the work and for pivoting the arm 12 in the opposite direction, and means for locking the arm 12. As shown, both arms 12, 13 are on the same pivot 11 and are moved by single-acting hydraulic jacks 18, 26 operated, through a three-position valve 32, by a footpump 29. After fixing a vehicle's floor to the beam 1 with the clamps 8, 9, the pump 29 is operated to bring a rubber ball 24 carried by the arm 22 against the vehicle's roof, and the cylinder 26 is isolated to lock the arm 12 in position. The valve 32 is then re-set for moving the arm 13, which is connected by a chain to the part of the roof straightened, the straightening force thus passing through the roof and being resisted by the ball 24. A socket 35 at one end of the beam receives a lateral beam, Fig. 3 (not shown).
